To all whom it may concem:

Be it known that I, ELLswoRTH E. FLORA, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement i-n Boxes, of which the followingis a specification.

My invention relates to an improvement in boxes which I have devised,more particularly, for use in paper-board or fiber-board boxes to enablethem to be provided with countersunk or in set heads fastened in placeby rivets, eye suitable securing means applied to mutually overlappingreinforcing flaps of the boxbody and heads; the primary object being toprovide a peculiarly strong and neat box ofthe material referred to.

In the accompanying drawings, Figure 1 is a perspective view of a box ofmy improved construction, showing the heads in unassembled relation tothe box-body; Fig. 2 is a similar view of the complete box; Fig. 3 is anenlarged broken section on line 33, Fig. 2, and Fig. 4 is an enlargedsection on line 4-4, Fig. 2; Figs. 5 and 6 are plan views of'the blanksrespectively for the body and one of the two similar heads of the boxofFig. 2; Fig. 7 is a broken perspective view showing a modifiedconstruction of thebox, one head be ng re resented in unassembledrelation to the boxody; Fig. 8 is'a broken perspective view of the ofFig. 2 embodying the modified construction; Fig. Q'isan enlarged sectionon the irregular line 9-9, Fig. 8, and Figs. 10 and 11 are plan views ofthe blanks respectively for the body and-head of the modifiedconstruction.

The box-body 12 and the simjlar heads 13 of the construction shown in'-Fig. 1 are produced, respectively, fromblanks 14 (Fig. 5) and 15 (Fig.6), the blanks" being cut from fiber-board or ulp-boa'r'd"? as thepreferred material. The lank 14 for .the box-body of rectangular shapeis a strip of thematerial creased transversely at. suitable intervals toform sections, as indicated by dotted lines, to adapt it to be foldedfor producing the body 12 with one section forming the cover 112provided with a flap 212 through which to fasten it by staples, asshown, or. 'other- Wise, to the-adjacent side of the body, which itoverlapsf The blank 14 also has fla s 114 extending laterally atintervals from t e ermanently j ets or other opposite edges of alternatesections, these flaps being rendered readily foldable by creasesextending lengthwise of the blank, as indicated by dotted lines. Theblank15, which is the same for each head 13, has flaps 115 extendingfrom two opposite edges like the flaps 114, and two wider flaps 215extendin from its other edges, each adapted to' be fo 'ded lengthwiseupon itself, as Well as at its junction with the body of the blank.

With the box-body roduced in the-form represented in Fig. 1' rom a blank14, and heads 13 produced in the form shown from blanks 15 and ofdimensions ada tingthem to be inserted and countersunk into the openends of the body, in inserting a head into place its folded flaps 115encounterthe extremities in their paths of the box-body and theseextremities present abutments against inserting the heads too far,whereby the outer edges of the flaps 115 register with the bases of theflaps 114, which are folded inwardly againstthe flaps 115 and fastenedthereto by the rivets shown passed through three thicknesses of thematerial, or other suitable means; and the flaps 215, which embrace theadjacent end-portions are similarly fastened thereto, thus rendering thebox there also of triple thickness. As will be understood-owing, to thestop-function of the'flaps 215 it is practically impossible, inassembling the parts of the box, to insert the head 13 so far as to takethe flaps 115 out of such registration with the flaps 114 as would tendto cause staples, rivets, eyelets, or the like, driven through the flaps115, to miss the flaps 215, as might easily ensue in the assembling werethe stop-fla s omitted; and the function of the mutua I y overlappingflaps 114 and 115 is to resist tendency to displacement of the heads bybeing forced outwardly under pressure within the boy orcrushing-pressure exerted upon it.

The construction thus described is'peculiarly effective in rendering abox made of inherently weak and flexible material, such as pulp-board,adequately strong as a ship-- pin -box for merchandise, inasmuch as itena les the countersunk heads, which of themselves brace the structure,to be used in a more effective manner by locking them againstdisplacement in either directionthat is outwardly or inwardlyand inci'dentally reinforcing the box with a plurality of thicknesses of thematerial about the ends Where it is subjected to the hardest usage inhandling.

The modified construction illustrated differs from that described onlyin applying to the heads the opposing interlocking functions of theflaps on each of the four sides of the box. To accomplish this result,each section of the blank 16 (Fig. 10) defined by the transverse creasesindicated by dotted lines, is provided on each of its lateral edges withtwo short flaps 116 forming between them a recess 216; and the blankterminates at one end in a tongue 212. The blank 17 (Fig. 11) for a head13 of the modified construction has extending from each edge a flap 117like the flaps 215, except that the outer folding section thereof isreduced in length to form a central tongue 217 adapted to fit in a space216. v

In assembling the parts to produce the modified construction of the box,with the blank 16 formed into the box-body 12 of Fig. 7, in inserting ahead 13, the folded tongues 217 of the flaps 117 pass through the spaces216 and stop the box-head against undue extent of insertion at each sidethereof, and folding the flaps 116 over and against the outwardly turnedflaps 117 obstructs the box-head against displacement in the outwarddirection. The heads are secured in place, as by staples or other fasandflaps folded upon themselves over the ends of the box-body and securedthereto, for the purpose set forth.

2. A box composed of flexible material, such as pulp-board, comprising abody-portion having flaps extending from opposite sides of each openend, and heads countersunk into the ends of the body-portion, said headshaving outwardly projecting flaps, upon which said first-named flaps arefolded, and flaps folded upon themselves over the ends of the box-bodybetween said sides, and fasteners penetrating the several thicknesses ofmaterial about each head, for the purpose set forth.
